Abstract

In this paper, we have proposed a full-wave approach to the analysis of the fundamental antenna effects in a circular-disk dielectric patch antenna on a thin substrate backed by a PEC ground plane and coaxially excited by a vertical electrical dipole. The method of analytical regularization combined with the Galerkin method has been used. Antenna characteristics, such as the surface and space-wave powers, directivity, radiation pattern, and radiation efficiency, have been obtained and analyzed for different values of the disk permittivity and frequency. The situation of surface-wave suppression in such antennas has been considered
